The Kapp Putsch, also known as the Kapp–Lüttwitz Putsch, was an attempted coup against the German national government in Berlin on 13 March 1920. Named after its leaders Wolfgang Kapp and Walther von Lüttwitz, its goal was to undo the German Revolution of 1918–1919, overthrow the Weimar Republic, and establish an autocratic government in its place. It was supported by parts of the Reichswehr, as well as nationalist and monarchist factions.

Wolfgang Kapp was a German conservative and nationalist and political activist who is best known for his involvement in the 1920 Kapp Putsch. He spent most of his career working for the Prussian Ministry of Finance and then as director of the Agricultural Credit Institute in East Prussia. During World War I, Kapp was a vocal annexationist and critic of the government's policies, which he saw as not aggressive enough. His strong dislike of parliamentary government and the Weimar Republic led him to take a leading role in the 1920 putsch that bears his name. Following the putsch's failure to overthrow the German government, Kapp went into exile in Sweden. He returned to Germany in late 1921 to appear in court, but died while under medical care before he could testify.
